Good Thinking!
I was looking through forum posts on Etsy this morning and came across this great idea! I love being organized so I love finding new and creative ways to get my life in order. This is perfect for crafting supplies, but could be used for many other things. The more detailed instructions are at the link below, but basically this is two bookcases attached at one side with a hinge so that it can be opened and shut. That way when you are done you can close it shut and it won't take up a lot of room. Plus, everyone will just think it's another piece of home decor!

This is the best organization idea for craft supplies that I have ever seen! Thank you so much for posting it!
